Hi David, I am having the same or a similar problem that sagive but I couldn’t solve it.

The problem occurs only when the first category is displayed. Instead of display every item in the correct order (Title-URL and descriptcion), I get the description on the title and URL of the category on the description.

Warning: fopen(/home/momilcsi/public_html/kpress/wp-content/themes/KnowPress Theme/style.css) [function.fopen]: failed to open stream: No such file or directory in /home/momilcsi/public_html/kpress/wp-includes/functions.php on line 4165

Warning: fread(): supplied argument is not a valid stream resource in /home/momilcsi/public_html/kpress/wp-includes/functions.php on line 4168

Warning: fclose(): supplied argument is not a valid stream resource in /home/momilcsi/public_html/kpress/wp-includes/functions.php on line 4171

And this in Manage themes :

Broken Themes

The following themes are installed but incomplete. Themes must have a stylesheet and a template.
Name Description
KnowPress Theme Stylesheet is missing.
